Today when I went out to the coop to fill the feeder and change out the water, I noticed one of my EE hens was rather loud. The noise seems to be the same as the other hens only substantially louder. It sounds like a screeching really. To me, it is like nails on a chalkboard or chewing on popsicle sticks. Ugh! I began to be concerned that perhaps she is sick. Aside from the screeching noise, she doesn't appear to be behaving any differently than the others at all. She doesn't care at all if I pick her up either. My dh suggested that perhaps she is having an issue with an egg. My flock is about five months old now and hasn't begun laying. Could this be a sign that she will be laying an egg soon? Could she be sick? Something else wrong?
